Leaded Petrol in a 2.0 16v

[surfer.vr6 0]

I am seriously tempted to put some 4-star (not lrp) petrol in my car.

The problem is, will the lead damage the lamba probe in my car?

My car has been decatted with a cat by-pass pipe.

 

You are probably wondering why i want to put 4-star in and not normal unleaded, well how does an average octane rating of 99.7 sound to you?!

 

Came across this site: http://www.leadedpetrol.co.uk/index.html

 

Tell what you guys think?

Do you notice a difference between normal and Optimax etc?

Yeah definately

 

The C feels so sluggish with normal unleaded so i dont tend to use it really, always go with optimax or ultimate.

 

My car seems to be really affected by what juice is in it!

 

I remember when i had my mk2 Golf gti 8v and when you put 4-star petrol in it, it felt like i had just unleashed another 10 or so horses! so much smoother and more torque it just really loved to rev. But then again that had no cat or lamba probe!

There wouldn't be any point in putting leaded fuel into your valver for a couple of reasons.

 

1. 4 star is (or was) 97 ron and optimax or ultimate is 98 ron so you woyuldn't be gaining anything from putting 4 star in.

2. It will probaly damage the oxygen sensor

 

Just my opinion :)

The only reason you might choose to use genuine leaded petrol is because you hate small babies and trees, and probably voted for George Dubyah, you evil person. ;)

Wouldn't it knacker the Cat as well, or am I thinking of something else?

yup, leaded petrol into a cat'd car will screw the cat and clog up the lambda... not a clever idea... :|
